Partial differentiability in all directions means that a function has partial derivatives with respect to each variable at a given point, and these partial derivatives exist and are continuous in all directions at that point. In other words, the function is differentiable with respect to each variable, and this differentiability holds true regardless of the direction in which the partial derivatives are taken. This concept is important in multivariable calculus and is a key property for determining whether a function is differentiable at a given point. **
